Fear of movement (kinesiophobia) seems to play an important role in the development of chronic pain. However, for temporomandibular disorders (TMD), there is a scarcity of studies about this topic. The Tampa Scale for Kinesiophobia for TMD (TSK/TMD) is the most widely used instrument to measure fear of movement and it is not available in Brazilian Portuguese. ⋯ Moderate correlations (0·40 < r < 0.60) were observed for 84% of the analyses conducted between TSK/TMD-Br scores versus catastrophising, depression and jaw functional limitation. TSK/TMD-Br 12 items and two-factor demonstrated sound psychometric properties (transcultural validity, reliability, internal consistency and structural validity). In such a way, the instrument can be used in clinical settings and for research purposes.

Recently, updated diagnostic criteria for temporomandibular disorders (DC/TMD) were published to assess TMD in a standardised way in clinical and research settings. The DC/TMD protocol has been translated into Finnish using specific cultural equivalency procedures. To assess the interexaminer reliability using the Finnish translations of the DC/TMD-FIN Axis I clinical diagnostic assessment instruments. ⋯ The NA was high (medians ≥87%) for all DC/TMD diagnoses, except for myalgia which showed acceptable NA (median 75%). The %A was high for all assessed diagnoses (medians >85%). The findings of this study showed DC/TMD-FIN Axis I to demonstrate sufficiently high reliability for pain-related TMD diagnoses.
